EncryptionConfig

Details required to encrypt a stream.

Field Type Label Description
encryption_keys EncryptionKey repeated List of encryption keys and associated information.

EncryptionKey

A single encryption key and associated information.

Field Type Label Description
key_id string Unique identifier for the key, as identified by your DRM provider, represented as 32 hexadecimal digits in UUID 8-4-4-4-12 format (for example, d569cb35-bd05-48c7-a99d-92feb381df13) or plain 32 hexadecimal digits (for example, d569cb35bd0548c7a99d92feb381df13).
key_uri string URI of the key. This URI is inserted into the M3U8 header.
key string 128-bit encryption key represented as 32 hexadecimal digits (for example, f828863735a2d93fd538f4b8e9b8bd80).
iv string 128-bit encryption IV represented as 32 hexadecimal digits (for example, 217719cae3ffc905b62a248956c9321f).
matchers EncryptionKeyMatcher repeated A list of rules indicating which muxStream(s) in your channel should use this key. A muxStream will use the first matching key it finds. If this field is omitted, all muxStreams will treat the key as a match.

EncryptionKeyMatcher

A single rule indicating which muxStream(s) in your channel should use the key.

Field Type Label Description
mux_streams string repeated A list of muxStream IDs which should use the key.

Scalar Value Types

.proto Type Notes C++ Java Python Go C# PHP Ruby
double double double float float64 double float Float
float float float float float32 float float Float
int32 Uses variable-length encoding. Inefficient for encoding negative numbers if your field is likely to have negative values, use sint32 instead. int32 int int int32 int integer Bignum or Fixnum (as required)
int64 Uses variable-length encoding. Inefficient for encoding negative numbers if your field is likely to have negative values, use sint64 instead. int64 long int/long int64 long integer/string Bignum
uint32 Uses variable-length encoding. uint32 int int/long uint32 uint integer Bignum or Fixnum (as required)
uint64 Uses variable-length encoding. uint64 long int/long uint64 ulong integer/string Bignum or Fixnum (as required)
sint32 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. int32 int int int32 int integer Bignum or Fixnum (as required)
sint64 Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s. int64 long int/long int64 long integer/string Bignum
fixed32 Always four bytes. More efficient than uint32 if values are often greater than 2^28. uint32 int int uint32 uint integer Bignum or Fixnum (as required)
fixed64 Always eight bytes. More efficient than uint64 if values are often greater than 2^56. uint64 long int/long uint64 ulong integer/string Bignum
sfixed32 Always four bytes. int32 int int int32 int integer Bignum or Fixnum (as required)
sfixed64 Always eight bytes. int64 long int/long int64 long integer/string Bignum
bool bool boolean boolean bool bool boolean TrueClass/FalseClass
string A string must always contain UTF-8 encoded or 7-bit ASCII text. string String str/unicode string string string String (UTF-8)
bytes May contain any arbitrary sequence of bytes. string ByteString str []byte ByteString string String (ASCII-8BIT)
